Description:
Wolfram Research, the maker of the popular software Mathematica, recently added a comprehensive database of mathematical functions to its Web site. There are tens of thousands of formulas that can be browsed alphabetically or divided into various categories. Documents explaining general identities and notations used on the site are also available; however, users must sign the guestbook before they can be viewed. Wolfram Research hopes eventually to add a history section for many of the functions, explaining their origins and significance. Although the list is huge, it is constantly growing. Contributions from the math community are welcomed and encouraged.
